Proposed MTA pulpotomy over CaOH2 pulpotomy due to a greater ability to maintain the integrity of pulp tissue, a thicker dentinal bridge, less inflammation, less hyperemia and less plural necrosis.
Witherspoon
94% of crown-fractured teeth (permanent incisors) treated with partial pulpotomy were successful
Fuks
"Dentinal" bridge formed after pulpotomy with CaOH2 is porous. 20-250 microns in size - dye leakage study
Goldberg
In crown-fractured teeth with vital pulp tissue after an exposure period of up to 7 days after injury, not more than 2mm of the pulp beneath the exposure needs to be removed. Partial pulpotomy can be performed for the effect of CaOH2 to be exerted on non-inflamed tissue
Cvek
Calcium hydroxide paste caused the characteristic well-defined zone of necrosis subjacent the past. With Dycal there was no zone of necrosis
Tronstad
Outcome predictors according to Ng
Level of obturation, quality of obturation, coronal seal, size of PARL, presence of PARL, sinus tract, perforation, patency, CHX use (decr), Flareup (decr)
Success of Sx
89% at 1+ years   -Tsesis
93% at 6-10 years - Song/Kim
Success of NSReTx
80/86% at 2 or more years - Ng
Success of NSRCT
83% with strict criteria, 89% with loose criteria at 2 or more years - Ng
86/95% at 4-6 years - deChevigny (Toronto Study)
88% at 20-27 years - Fristad/Molven
97% Survival, 3% that did not were more often not crowned  -Salehrabi/Rotstein
1.46 million sample size, insurance study
Decoronation
Malmgren
with continued alveolar growth, 1-2mm infra positioning and ankylosis
